Abstract
A modular rotary discoid valve assembly includes a housing for positioning on an engine the piston and cylinder type. The housing includes an intake passage for conducting a working fluid to the cylinder and an exhaust passage for conducting the working fluid from the cylinder. The housing is formed with an internal cavity which intercepts the intake and exhaust passages, which cavity contains a rotary valve member having a window whose shape and/or angular positions on the disc varies with increasing distance from the disc axis. The window is so positioned that when the member is rotated to a first angular position, the window is located opposite the intake passage whereby the working fluid can flow along the intake passage through the window to the cylinder and when the member is rotated to a second angular position, the window is located opposite the exhaust passage so that the working fluid can flow from the cylinder through the window along the exhaust passage. Thus, the assembly alternately opens and closes the intake and exhaust passages in a periodic manner. Preferably also, the valve assembly includes a throttle bar slidably mounted in the housing parallel to the rotary va…
